Application March 15, 1940, Serial No. 324,174

17 Claims.

This invention relates to beverage shakers, and more particularly to those of the type commonly -known as cocktail shakers-into which ingredients including one or more liquids may be loaded, with ice, for chilling and mixing.

It is generally desirable that the ingredients be brought into immediate contact with the ice, not only for maximum speed of chilling but, in the case of many cocktails, also for a certain slight initial dilution by melting ice during the mixing or initial preparationa dilution relied on in cocktail recipes generally, and universally inherent in good bar-prepared cocktails. It is equally undesirable, however, that the dilution of the cocktails should continue to take place while they, or any portion of them, remain in the shaker for any substantial time after initial preparation.

In my co-pending application Serial No. 243,225, iiled November 30, 1938, on which Patent No. 2,308,657 has since been issued, I disclosed several embodiments of a novel shaker arranged for extremely simple use, by which the ice is caused to be in contact with the ingredients during the initial preparation of the cocktails, and is thereafter (together with the water produced by its gradual melting) caused to be out of contact with the cocktails but in cooling relationship thereto. Thereby the desired initial dilution and rapid chilling are obtained, while the undesired continued dilution is completely obviated-Without, however, sacrificing the continued action of the ice and its melt (together conveniently termed ice-water) to keep the cocktails cold.

' The use of the shaker involves its suitable orientation at an appropriate time, the shaker being arranged thereupon to eiect and thereafter to maintain a segregation of the contained icewater and cocktails.

Among the objects of the instant invention are to provide an alternative embodiment, and an improved embodiment, of such a shaker.

It is an object to provide such. a shaker which may be manufactured simply, inexpensively, and in any of a variety of manners.

It is an object to provide a shaker adapted for use in the manner set forth, wherein the nonconventional portions are in the form of a unit removably inserted into a conventional type of shaker. And it is an object to provide a unit by which a conventional type of shaker may be converted into one adapted for use in the manner set forth.

It is an object to provide a shaker adapted for use in the manner set forth, wherein the main exterior portion may be of simple `lar formation without other parts permanently secured thereto, whereby simply formed glass or other transparent jars are rendered available for such portion, and will permit the continuous visual observation of the liquid actions caused to take place within the shaker.

Itis another object to provide a shaker adapted for use in the manner set forth and at the same time arranged for particularly easy and complete inspection and cleaning of all its parts.

It is an object to provide a shaker which, although loaded with approximately the full volume of ice and ingredients that a conventional shaker of similar overall size will hold, may nevertheless be eiectively used in the usual case in the special manner and for the benecial results above outlined.

It is a general object to provide an improved cocktail shaker.

Other and allied objects will more fully appear from the following description and the appended claims.

In the description reference is had to the yaccompanying drawings, of which:

Figure 1 is a perspective view of a shaker embodying my invention, a portion of the jar being broken away better to illustrate the unit removably positioned therewithin, and the cover unit being drawn somewhat upwardly from the jar and partially broken away for a similar purthrough the center of the shaker, the parts allA being in their assembled positions;

Figure 3 is a horizontal cross-sectional view taken through the shaker approximately on the line 3-4 of Figure 2;

Figure 4 is a fractional top plan view of the shaker with cover unit in place, showing the cap which is provided to close the pouring outlet in the position in which it is preferably put when removed from that outlet;

Figures 5 through 7 are simplied illustrations of the shaker in successive positions through which it may be usefully oriented immediately following initial mixing and chilling when it has been loaded to a fraction only of its capacity; and v Figures 8 through 10 are similar illustrationsv of the shaker in successive stages of its use fol- Figure 5-6-'1 positions as hereinafter more fully described.

Reference being had to Figures l and 2, it will be seen that the main exterior portion of the illustrated shaker is in the form of a simple jar I. Preferably this is of glass or other transparent material. I'he lar has been shown as of substantially cylindrical shape, or without appreciable taper of its diametertoward its base. 'Ihe cylindrical shape I have found both to be attractive in appearance and, when selected to have an outside diameter (for example of the order of 35/2" or 3%") permitting its secure holding by a single hand, to have the advantage that it can be grasped as readily near its center of gravity as elsewhere. It is, however, to be understood, as will be appreciated as the description proceeds, that the general features of my invention are in no way limited to incorporation with a cylindrical jar. 'I'he jar I may be provided with the rounded top edge 2 in accordance with conventional practise.

The exterior of the illustrated shaker is completed by a cover unit 2li. 'Ihis may comprise an inverted cup-shaped cover 2|, its extreme bottom (open-end) portion 22 being of a. diameter appropriate to be fitted snugly around the outside top portion of the jar I. The portion 22 terminates in anA inwardly directed shoulder 23 adapted, when the cover is in place on the jar, to bear against the top edge 2 of the jar; the shoulder is preferably fairly sharply formed, and is preferably of a dimension such as to leave the internal diameter of the cover immediately thereabove at least as great as the internal diameter of the jar I at the top of the latter.

While no limitation as to the material of the cover is intended, I may mention as typical a metal such as brass or aluminum.

From the shoulder 23 the cover is extended upwardly to form a side portion 24, and finally is curved inwardly to terminate in a top 28. 'I'he side portion 24 has been shown as substantially cylindrical, and the top 26 as substantially planar, and as being separated from each other by a small-radius curved portion 25. 'Ihe cylindrical shape of the side portion 24 I have found both to be pleasing in appearance (particularly when a cylindrical jar I is employed) and,'for reasons hereinafter apparent, somewhat advantageous functionally-at least when the diameter of the shaker at its top is limited to the general order ofmagnitude mentioned above as typical for a cylindrical shaker. 'Ihe planar shape of the top 26 I have found to carry out a pleasing appearance, to be functionally advantageous in connection with the detail feature of the retention of the pouring-outlet cap when not in use, and to be somewhat advantageous in a general functional sense-particularly under. the. conditions mentioned at the end of the preceding sentence. It is, however, to be understood that the general features of my invention are not limited to incorporation with covers of the cylindrical-side planar-top shape illustrated, but may usefully be incorporated in shakers having covers whose shape departs widely therefrom.

A pouring outlet is provided in the cover, preferably in a position such that a complete discharge of cocktails from the shaker may be effected by an orientation of the shaker from normal verticalposition to little more than horlzontal. I have illustrated such an outlet as 28, formed by a short tube secured to the periphery of a suitable aperture provided in one side of the top 2B and in the adjacent part of the curved portion 25, and extending diagonally upwardly and forwardly therefrom. (The terms "front" or forward" and their derivatives are here and hereinafter employed to denote the direction toward which the shaker is oriented for pouring through the outlet 28, or a leftward direction as appearing in Figure 2, and the terms rear or rearward and their derivatives to denote the opposite.) The illustrated and preferred construction causes the most forward part of the outlet 28 to extend substantially from the most forward part of the cover side portion 24, facilitating the complete cocktail discharge as above discussed.

A cap is provided for the pouring outlet 28; this may be in the form of a shallow inverted cup adapted to t over and frictionally engage the outlet tube. The axis of the cap when in place on the outlet will of course coincide with that of the outlet-described above as preferably somewhat diagonal-and the top of the cap when in position will therefore be somewhat inclined. I have preferred, however, that the top edge 29 of the outlet, exposed when the cap is removed, be in an essentially horizontal plane (e. g., parallel with the cover top 26). This feature, as well as the provision of the outlet in the top rather than the side portion of the cover, while neither is indispensable, both have the advantage of facilitating the observance of the discharge from the outlet by the manipulator of the shaker.

Ihe diameter of the pouring outlet is preferably made large enough so that even upon an orientation of the shaker sufficient to result in a considerably abnormal or excessive rate of discharge of cocktails from the outlet, the cocktail level at the outlet will not have risen sufficiently tostop the free ingress of air through the then-upper portion of the outlet to take the place of discharged cocktails.

The description of the cover unit may be completed by reference to and explanation of the joint functions of a handle 3| provided thereon. 'I'his handle may be in the form of a wide. shallow, inverted U, extending in a vertical plane transverse to the front-and-back plane of the shaker and somewhat behind the center of the shaker, the downwardly directed ends of the handle being secured to the cover top 26. Typically the handle may be formed of a suitably bent rod, its extremities being suitably shouldered, passed through holes in the top 28, and peened over on the inside of the cover top as at 82 in Figure 2. One function of the handle is of course the facilitation of the removal of the cover unit from the jar i, on which it may seat so tightly as to occasion some trouble in removing it in the absence of a convenient finger-hold; the illustrated handle is very well adapted to this function, since it permits several lingers to be si. multaneously slipped under it, and this in turn permits a sideward rocking force to be applied to the cover unit.

The other function of the handle 3| is, either alone or in cooperation with the outlet tube 28, to form a retaining means for the cap 30 when that is removed from the outlet. The spacing between the horizontal portion of the handle and the cover top 28 is made great enough to admit the vertical dimension of the cap; the latter may therefore, immediately upon its removal from the nearby outlet 28, be slid from the rear under the handle. The spacing abovementioned may if desired be made just small enough so that handle and the top 26-an action which is made possible by the natural slight resiliencies of the handle and cover top. Such frictional retention is not, however, necessary. The horizontal spacing of each of the vertical legs of the handle from the outlet tube 28 may -be made somewhat less than the diameter of the cap, and on forward orientation of the shaker the cap will gravltate to and be retained in Aone of the two positions illustrated in dash-dot lines in Figure 4-beyond which it cannot go in view of the sta-ted horizontal spacing. This provides a quite suillcient retention, as it is proof against all excepting substantial rearward orientation of the shakerwhich does not have to be indulged in when the cap 30 is removed from the outlet.

No claim is made herein to the feature of cap retention by the handle 3| or outlet tube 28, that subject matter being disclosed and claimed in my co-pending application Serial No. 508,833, illed November 3, 1943, as a division of this application.

It will be appreciated that the shaker as so f ar described, while involving a few preferred departures from conventional construction, is one adapted for use in the entirely conventional manner-of both original placement, and continued retention throughout the use of the shaker, of ice and ingredients in contact with each other. I shall now, however, proceed to describe the further elements of the shaker which adapt it to use in the special manner, and for the improved non-continued-dilution but continuedcooling-iniluence functions, early above outlined. These elements are preferably comprised in a unit 3 removably inserted in the jar I, and have been so illustrated and will be so described. It is, however, to be understood that the novel features residing in and resulting from the combination of the unit 3 with the hereinabove described elements of the shaker constitute an aspect of my inventionv independent of whether or not they are arrived at by a removable-unit construction.

The lower portion of the unit 3 may be termed a sump 6. It is desirable that this be confined on one side (to be the forward side) of a nearly vertical plane passed through the shaker, on the other side of which plane there will lie a substantial fraction (such as a half) of the space enclosed by the shaker. It is also desirable that the open top of the sump have -a considerable area. I have therefore preferred, though it is not indispensable,.to employ a sump whose open top (da) is of approximately semi-circular horizontal configuration; whose front and lateral sides are substantially in the form of a single part-cylinder (whose axis will, when the unit is in place, approximately coincide with the axis of the shaker) extending downwardly from the arc of the semi-circular top lia; wh'ose rear side Y is substantially a plane extending downwardly from the chord of the semi-circular top 4a; and whose bottom 1. is closed as by an extension of one of the side elements of the sump (e. g., 5) to meet the other. `The capacity requirement of the sump does not typically necessitate a full semi-circular cross-section all the way down to the bottom. Therefore the rear side II may extend not only downwardly but at the same time somewhat forwardly; and the rearmost portions la of the part cylinder 5 may be somewhat displaced, progressively toward the bottom, toward each other from their truly cylindrical positions,

and may typically join the rear side 8 along straight lines 3a.

As will hereinafter more fully appear, the unit 3 is typically held in place in the shaker with the front side 5 of the sump in fairly close spaced relationship to the inside' of the front of the Jar I. It will therefore be understood that some of the more detailed description above of the typical sump shape is presented simply for the illustrated case of a cylindrical Jar I.

The upper portion of the unit 3 may be termed an ice-cage 8. Part (typically approximately the front half) of the bottom of the ice-cage is open into (and may typically coincide with the top 4a of) the sump d; the front and lateral sides 5' of the ice-cage may therefore be formed ii desired as an upward continuation of the part cyl- Vaperturing has been simply illustrated by the series of slots I0, which extend forwardly to terminate at short distances behind the sump.

In their upper portion the sides 5 of the ice-` cage 8 desirably extend rearwardly somewhat beyond the center of (or central vertical transverse plane throughl the shaker, for example to have their rear edges 5a' approximately along projections of the diagonal upward-rearward lines 6a abovementioned. Immediately above the plate 9 the sides 5 of the ice-cage 8 are extended for a distance rearwardly along the side edges of that plate and are secured to those edges; therefrom the rear edges 5c' of the lower 4portion of sides 5 may extend diagonally upwardly and somewhat forwardly to merge with the edges 5a' abovementioned in softened angles 5b.

At the top of the unit v3 the sides 5' of the icecage 8 may curve inwardly into a top I I, which may typically be approximately planar. .The rear edge I Ia of the top may join together the edges 5a abovementioned; desirably the edge IIa,

rather than being a Vstraight line joining the edges 5a', will be in the form of a very wide V, with forwardly directed, rounded or softened apex IIb, preferably located slightly to the rear of the axis of the shaker.

Externally the unit 3 is provided with two spacing means I2, each somewhat displaced in a respective lateral direction from the center of the front of the unit. These spacing means may be in the form of vertical ribs formed in or secured to the unit, and extending outwardly therefrom for a short distance (typically 1/8 inch or slightly more); vertically they may extend, if desired. not only along the upper portion of the sump t but also along the lower portion of the ice-cage 8 as well. When the unit 3 is positioned in the jar I these spacing means are held in contact with the interior wall of the jar, locating the entire unit laterally therewithin. The means for holding them in such contact may be a suitably formed spring I3; this may for example be secured to the bottom of the plate 9, and may rst extend downwardly therefrom and may then be curved rearwardly, upwardly, and finally horizontally into an almost-closed approximate circle.

The spring is formed so that its rearmost'portion will be forced slightly forwardly by the jar as the unit is inserted thereinto, the spring thus being placed in slight constraint and so remaining while the unit is in the Jar. The friction of the spring and the two spacing means I2 against the jar is sufllcient so that the unit ls retained longitudinally in its normal position (of contact with the bottom of the jar) during all normal usages of the shaker.

There is of course no unique laterally angular relationship to be observed between the unit 3 and the Jar I, in view of the sameness of all circumferential portions .of the jar. A particular relationship should, however, be observed between the unit 3 and the cover unit 20; this is a relationship of substantial centering of the pouring outlet 28 over the central front portion of the unit 3. To enforce the assembly of the cover unit onto the jar in its proper relationship to the already-inserted unit 3, the latter may for example be provided with a projection It adapted to extend from inside the cover into the pouring outlet 28. This projection may for example be a wide, inverted U, which may if desired be assembled to the top II of the unit 3 in similar manner to that above described for the securing of handle 3I to the cover top. It may be positioned in a vertical, transverse plane which, when the cover is in place, will approximately bisect the pouring outlet 28; it may have an overall width almost as great as the diameter of that outlet; and it may be high enough to impinge on the bottom of the cover top 26, in the random assembly of the cover unit onto the jar, considerably before any seating of the shoulder 23 on the jar edge 2. In putting on the over unit one may simply let the inside of its top rest on the projection I4, and then rotate the cover unit until the outlet 28 settles over one or the other of the rounded angles Illa of the projection and so assumes its proper angular position relative to the unit 3. When the cover unit has been assembled to the jar I, the top and the upper side portions (both front and lateral) of the unit 3 will typically be in slight spaced relationship to the inside of the coverthe front and lateral side portions of the rest of the unit 3 being typically in similar spaced relationship to the jar i whenever that unit is in the jar.

While the unit 3 has been illustrated as formed of thin material, appropriate to its manufacture from sheet stock and juncture of separate portions along the edges of sump-side 6 and plate 9, it will be understood that no limitations are intended as to the method of its manufacture, the choice of what portions are to be made integral and what separate, the selection of points of juncture, etc.. as it will become obvious that these may be widely varied without impairing the effective function of the device or departing from ,the spirit of the invention. And While I have preferred to make the unit 3 of metal, for most efficient temperature-maintenance characteristics in the use hereinafter described, the requirement for eiciency in this respect is not so great as to preclude the satisfactory use of whatever material or materials best lend themselves to the fabrication of the unit in any particular case.

Consideration being given to the structure as presented by the unit 3 inserted into the jar I, but without the cover unit 2l in place, it will be seen that the upper rear portion of the jar I provides a rear wall for the ice-cage 3 for a major fraction of the height of the latter (reliance on the jar for this rear wall being preferable to the incorporation of'such a rear wall in the ice-cage itself, both on account of simplification of structure and on account of the resulting appreciable increase of the capacity of the ice-cage). The very top rear portion of the icecage is. however, freely open for loading-the extension of the ice-cage materially above the top of the Jar I being desirable in this respect. Essentially two receptacles are provided. A first is that formed by the ice-cage 8 and communicating sump 4; the other is that provided by the portion of the jar interior surrounding the sump.

The two receptacles communicate with each other through the slots Ill in plate 9; through the semiemular space P1 between the free periphery o! the plate 9 and the jar l; and through the narrow space P2 separating the ice-cage edges 5c' and sides 5' from the jar I.

With the cover unit 23 in place, the structure provides two compartments-the first being that formed by the ice-cage 8 (considering its upper rear portion to be bounded by the portion oi?v the cover 2l positioned thereacross) and communicating sump t, and the second that provided by the jar interior surrounding the sump. These compartments communicate with each other through the slots I0 and spaces P1 and -P2 abovementioned, augmented by the narrow space Pa between the ice-cage edges 5a' and Ila and top II and sides 5', on the one hand, and the interior of the cover 2l on the other. 'Ihe principal portion of the second receptacle or compartment is of course disposed behind the first; but the outlet 28 forms a forwardly directed outlet for liquid from the second receptacle or compartment, leading upwardly from the top front region of that compartment through the narrow partial-annular space or passage Q between the sides 5' on the one hand and the interior of the jar and cover on the` other-the passage Just describedleading around, and more specifically in front of, the rst compartment or receptacle.

Consideration may now be given to the use of the shaker. With the cover unit 20 removed but with the unit 3 in place in the jar I, ice is dropped into the ice-cage 8, some of the initial pieces of course falling on down into the sump 4; the icecage and sump may be quite filled if it is intended to use substantially all the capacity of the shaker, or if it is expected that continued cooling over a particularly protracted period will be desired. Thereafter the ingredients may be poured (and solid ingredients, such as sugar, dropped) into the shaker. It will be most convenient to insert them into the ice-cage; this, however, is not essential, and in any event the excess of ingredients over a few ounces will, in view of the ice already in the sump be forced toflow out of the sump and ice-cage through slots I0 and spaces P1 and Pz into the shaker at large. The loading with ingredients may be carried to any length, limited only by the top of the jar I; and it may be noted that the extension of the ice-cage 8 materially above the top of the jar, and its ability to retain ice in this extending portion, may actually permit the loading of the shaker with a volume of contents greater than could be retained in the jar I without the unit 3. During the insertion of the liquid there will, of course, be some melting of the ice as a result of the relatively warm liquid flowing thereover (this performing some of the intended initial dilution); this will reduce the top level of the ice in the ice-cage, and a few more pieces of ice may, if desired in cases of quite full loading or the like. be inserted at the top of the ice-cage after the liquid insertion.

It will of course be understood that, if preferred, the ice-cage and sump (i. e., the unit 3) may be loaded with ice while out of the jar, and thereafter inserted into the jar, into which the ingredients may if desired have already been loaded.

After the loading has been completed the cover unit 20 may be assembled to the jar, with cap 30 in place over outlet 2B, and the entire shaker agitated for mixing and chilling of the contents. The ice is of course entirely retained in the compartment formed by the ice-cage 8 and sump 4, in view of the narrowness of the passages abovementioned through which this compartment communicates with the other, and the agitation must therefore serve to introduce the liquid into this compartment. It is of course not necessary, however, that all the liquid be simultaneously in this compartment, and it is suiilcient if portions of the liquid are successively introduced-the liquid diffusion in the agitation automatically insuring that each successive portion will be largely made up of fresh parts of the liquid. A satisfactory, though non-limitative, manner of agitating is to hold the shaker with its axis either horizontal or inclined and with the front of the shaker upwardly directed (as shown in either Figure 5 or Figure 6), and to reciprocate it smartly along the line of its axis if solid ingredients or the like are to be dissolved or dispersed through the cocktails,

-or to rock it in see-saw fashion (from the Figure 6 position to a corresponding position on the other side of horizontal) if the nature of the cocktails does not demand such violent agitation. If preferred, however, the shaker may be held in substantially fully inverted position, and agitated in more or less the conventional manner. With any of these or still other manners of agitation, the communication provided between the compartments has been found ample to insure a thorough cooling of the cocktails in a time negligibly longer than required when ice and ingredients are, as conventionally, in entirely free communication with each other.

At the conclusion of the agitation the shaker may be held in approximately the Figure 5 position (front up) and the liquid level noted in relation to the rear side (now downwardly directed) of the sump t. If that level can be brought appreciably below that side of the sump (as will be the case when the shaker is being used for moderate fractions of its total capacity), the shaker will be momentarily held, as illustrated in Figure 5, with that sump side inclined very slightly downwardly toward its top; this positively insures the absence of any cocktails from the sump. Then the shaker will be restored to the vertical position illustrated in Figure 7, passing through the inclined position illustrated in Figure 6. Excepting in the case of quite unreasonably abrupt movement of the shaker in this restoration, the ability to keep the angle A (formed between the sump rear side 6 and the rear bottom portion 9 of the ice-cage) above the liquid level L insures that no cocktails will pass back into the sump during the restoration. At the conclusion of the restoration the liquid level will be slightly or con.. siderably below the angle A, according tc the original loading, and the cocktails will all be in the second compartment (that external to the sump and ice-cage) On the other hand all the ice (now considerably less in volume, and furthermore of shapes capable of more compact storage, than when originally loaded) will be in the first compartment: at least some of the ice will be in the sump. Occasionally some ice may also rest on the plate 9, but melt from this falling through the slots I0 into the cocktails therebelow offers a negligible problem-for this ice may be dislodged into the sump by a slight forward rocking of the shaker, a rocking which will probably be promptly administered in any event as a first incident of pouring.

The cap 30 may now be removed (and conveniently placed under the handle 3|), and the cocktails poured, as desired, by forward shaker orientation. They of course reach the pouring outlet 28 through the narrow partial-annular passage Q abovementioned. During the pouring the cocktailsare fully prevented from entering the first compartment by the ice-cage sides supplemented by the unperforated front portion of the plate 9 if the initial cocktail level during this phase of use is as high as the level L in Figure 7. Even in this limiting case the level to which the cocktails will come at the inception of pouring is approximately that indicated by the dash-dot line M in Figure 7. The illustrated position of the line M assumes that during pouring the center of the outlet 28 has been maintained in a vertical plane passing through the axis of the shaker-in other words, that there has been avoided any slight rotation of the shaker about its axis during the pouring orientation. It is to take care of the possibility of slight incidentalr rotations of that character that the edges 5c' are carried back, slightly more than otherwise theoretically necessary, to the illustrated positions, and that the inward extension of the slots i@ in plate 9 has been progressively reduced to the right and left of the front-and-back central vertical plane of the shaker, as best seen in Figure 3.

The required pouring orientations of course become progressively steeper as the cocktails are used up; and the ice-water in the sump d will advance along the front of the sump and icecage to progressively greater extents with successive orientations, eventually impinging on the top il of the ice-cage. But even with an appreciably more than i-degree pouring orientation (which is the approximate maximum required for complete cocktail discharge), augmented by some developed momentum of the ice-water, the top and lateral sides of the ice-cage are sumcient to prevent the egress of any of even a full-sump complement of ice-water out of the rst (or sump-icecage) compartment. If the pouring orientation could be depended on to be n strictly accurate forward one, a straight rear edge for the top Il passing through the position of the apex IIb would be suiiicient for this purpose; it is to take care of such incidental rotations about the shaker axis as above discussed that the edge iid has been made slightly V-shaped, and that the upwardly extending edges Ea' of the sides are correspondingly somewhat more rearwardly directed than would otherwise be necessary to meet the edge lla. It mayL here be mentioned that while the shaker would function fully as well for its separationmaintaining functions if the indentations pro,` vided by the apex Hb and the angles Eb' were omitted (i. e., filled in), I prefer to employ those indentations to facilitate inspection of and implement-access to the interior of the sump, which is appreciated at times of washing the unit- Also the indentations tend at least slightly to increase the ice capacity of the ice-cage.

The. description of operation so far presented has concerned that use of the shaker which emice-cage.

ploys the second or storingcompartment up to its full capacityi. e., up to the bottom plate 9 of the In review thereof, it will be seen that the transfer passage between this compartment and the othercomprising slots I and spaces P1, Pa and Pa-is positioned during the pouring orientations in ineffective relationship to both the ice-Water and the cocktails in the respective compartments. Otherwise expressed, the sump sides and 6 and the ice-cage sides B' and top il and inner portion of bottom 9 act during pouring orientations to prevent the co-mingling of icewater and cocktails, to shield the outlet 28 from the ice-water, and to shield the transfer passage from both ice-water and cocktails.

It may be noted that although the second orV storing compartment is principally disposed behind the rst, a portion of it extends around the sides and front of the first compartment, the lower portion of which becomes immersed in the stored cocktails. This construction gives an especially large surface for thermal transfer between the two compartments. Furthermore large portions of the unit 3 are flowed over by the icewater during each pouring orientation, while at the same time the narrow passage through which the discharging cocktails must ow forces them just prior to their discharge into very close relationship to those unit portions. These various features so contribute to the eiliciency of the cold-maintaining function that a satisfactory action may be had even though the Jar I and sump l be of materials of somewhat similar thermal characteristics. When, however, the jar is of transparent non-metallic material and the sump at the same time of metal, as I prefer, an extreme of emclency is obtained.

It has been pointed out above that the shaker may be used when loaded to its full capacityin which case an observation made 4in approximately the Figure 5 position of the shaker at the conclusion of agitating will reveal a liquid level above, rather than below, the rear (downwardly directed) side of the sump, typiiied by the liquid level in Figure 8. Under these circumstances the shaker will forthwith be stood upright, the liquid level becoming typically that shown in Figure 9; the cap 30 will be removed, and the initial cocktails will be poured without any immediate eiort to segregate cocktails from ice.

Theoretically a continued melting and dilution may occur at this stage. But it is to be borne in mind that in practice such full loading of a good-sized shaker is almost never indulged in unless the number of people drinking the cocktails is appreciable; and the chances are that several drinks will be poured in a very short length of time, if not immediately, after the loading and agitating and placement in the Figure 9 position. Thus in practice the level of cocktails within the shaker may rapidly be reduced to less than the capacity of the storing compartment, as illustrated typically in Figure 10. As

soon as this has occurred, the few or several ounces of cocktails remaining with ice in the sump may be transferred to join those in the storing compartment, by orienting the shaker from the Figure 10 position through the sequence of positions shown in Figures 5-6-'7-and negligible dilution suiiered in the average case. From this point on, of course, the use of the shaker is identical with that above described.

I'he capacities and dimensions of the various parts of the shaker will of course be somewhat inuenced by the external shape it is desired to employ, the maximum capacity thought necessary, and the like. These general considerations being settled, the inter-element apportionments may be approximately determined on in the light of the foregoing description. I have found preierable that the sump have a capacity of approximately 1A; to or ofthe general order of 1A, of the jar capacity; that it extend upwardly to a point approximately 1/2 to or of the general order of 2,5, of the way from the bottom to the top oi the jar: and, as abovementioned, that it be at least principally coniined on one side of a nearly vertical plane on the other side of which will lie a space of the general order of half that enclosed by the shaker-and so much of this space as lies within the jar may advantageously be even greater than half of the total space within the jar. These criteria greatly aid in securing an emcient utilization of space-for example, a storing compartment of the order of half the jar capacity, and so coniigured that in the average case the amount of liquid contents which can Just be collected under the sump (Figure 5) will just ll that compartment (Figure 7 i In a spirit which is primarily illustrative rather than limitative, I present below the major data relating to a typical practical embodiment of the shaker, and to its typical full-capacity use.

A jar was employed having a total capacity of 42 oz., and a cover unit which from the shoulder (23) upwardly enclosed approximately 10 oz. of space. The angle (A) at the top of the sump was arranged laterally about through the axis of the jar, and vertically at about 173 of the distance from the inside bottom to the top of the jar, so that the total enclosed space below it was about 28 oz. The sump, substantially o f the configuration illustrated, had a capacity of about 8 oz., and the storing compartment therearound sump were first fully loaded with fresh ice cubes aggregating. about 13 oz. (by weight or volume of contained water); thereafter approximately 29 oz. of liquid ingredients were introduced. The initial melting and compacting of the ice rendered its level in the cage low enough so that an additional 3 oz. (by weight or volume of contained water) were additionally accommodatedmaking a total of 16 oz. of ice and 45 oz. total (on a liquid basis) of inserted contents. After chilling the liquid level was of course above the top of the jar (permissible in view of the usual Watertight fit of cover to jar), and the pouring of about 18 oz. of cocktails in a short space of time reduced the liquid level to approximately that shown in Figure 10. Thereupon the residual cocktails in the sump were cleared therefrom into the storing compartment, which became lled almost precisely to its 2li-oz. capacity (as in Figure 7). Obviously about 7 oz. of ice was left in the sump-which was verified, after leisurely use of the 20 oz. oi' cocktails from the storing compartment, by measurement of the ice-water contents of the simip.

- Thus from a full loading a maximum of approximately 38 oz. of chilled and essentially normal-strength cocktails are obtainable from this shaker, and out of this or any smaller quantity the use of 20 oz. can be protracted over a very greatly extended time without sacrifice of coldness or strength. With a, full loading of the shaker without the unit 3, a proportionate amount of ice being used in the total 42 oz. of insertable contents, some 35i/2 oz. of cocktails might be obtained at normal strength-though only if poured essentially immediately after mixing. Thus in its complete form this shaker may be said to have a total capacity of about 107%, and a protractedtime capacity of about 56%%, of its immediateuse capacitynconventional f orm--from which latter anyprotracted time ability at all to deliver cold and normal-strength cocktails is absent. It is finally to be recalled that absolutely full-capacity loadings of cocktail shakers are unusual, andthe 561/2% gure represents to 3A of the volume of typical maximum loadings. if not the entirety of most loadings.
